What is uninterruptible power supply (UPS)?
A UPS uninterruptible power supply is a device the allows a computer to keep operating for at least a short time when the main power source is failed.UPS devices also protect from power surges. A UPS incorporates a battery that “kick in” when the device senses a failure of power from the primary source.If an end-user is operating on the computer when the UPS notifies of the power loss,they have time to save any data they are working on and exit before the secondary power source (the battery) runs out .When power surges occur,a UPS prevents the surge so that is does not damage the computer.While UPS systems are generally called double-conversion,line-interactive,and standby designs,these names have been used differently and manufacturers implement them differently-at least one system enables any of the three modes.
Function of uninterruptible power supply
Purification function: harmonics cause great pollution to the power grid, through IGBT rectification can improve the efficiency of power supply and reduce harmonics.
Ac voltage regulation function: after the rectifier of UPS, the power grid is changed into DC power supply, and then through the inverter into AC power output, the output power supply has a stable voltage and frequency.
Uninterruptible power function: when there is a power outage, the battery pack in the UPS system will supply the power to the user terminal after the IGBT inverter.
